Abstract	Ras-associated domain family 1A (RASSF1A) is a putative tumor suppressor gene located at 3p21.3, and the epigenetic inactivation of RASSF1A by hypermethylation of CpG islands within the promoter region has been observed in various cancer types, including prostate cancer (PCa). However, results from published studies on the association between RASSF1A promoter methylation and PCa risk are conflicting and inconclusive. Hence, we conducted a meta-analysis of 19 eligible studies with odds ratio (OR) and its corresponding 95% confidence intervals (95% CI) in order to investigate the strength of relationship of RASSF1A promoter methylation with PCa risk and its clinicopathological variables. Overall, the RASSF1A promoter methylation was significantly associated with PCa risk (OR = 9.58, 95% CI 5.64–16.88, P heterogeneity <0.001) and Gleason score (GS) (OR = 2.58, 95% CI 1.64–4.04, P heterogeneity = 0.019). In addition, subgroup analysis by testing material demonstrated the significant association between RASSF1A methylation and GS (OR = 3.09, 95% CI 1.92–4.97, P heterogeneity =0.042), PSA level (OR = 2.75, 95% CI 1.67–4.52, P heterogeneity = 0.639), and tumor stage (OR = 1.74, 95% CI 1.05–2.87, P heterogeneity = 0.026) in tissue rather than urine samples. In conclusion, this meta-analysis suggested that RASSF1A promoter methylation was significantly associated with an increased risk for PCa; furthermore, the RASSF1A methylation status in tissue rather than urine was positively correlated with GS, serum PSA level, and tumor stage, which can be utilized for the early detection and prognosis prediction of PCa.
